我队五号机在铅锌矿勘区采用SC-56金刚石绳索取心钻进。从1985年8月起共开动台月8.88,完成进尺10543.57m,平均台效1187.34m/台月,最高台效1739m/台月;其中,绳索取心钻进台月7.59,进尺10088.36m,平均台效1329.16m/台月,最高台效1905m/台月。竣工钻孔71个,优质孔65个,占91.55%,合格率100%。现场具体情况简述于后:
Our team of No. 5 machine in the lead-zinc mine exploration area using SC-56 diamond rope coring drilling. From August 1985 onwards, a total of 8.88Tunyue was completed. The footage was completed at 10543.57m, with an average effective efficiency of 1187.34m / station month. The maximum station efficiency was 1739m / station month. Among them, the cable was corroded into 7.59 in Taiwan month with a footage of 10088.36m, Taiwan effect 1329.16m / Taiwan month, the maximum Taiwan effect 1905m / Taiwan month. The completion of drilling 71, 65 high-quality holes, accounting for 91.55%, 100% pass rate. Site specific situation outlined in the post:
